Description
本出願は、2019年6月26日に出願された米国仮特許出願62/867,045号に基づく優先権を主張するものであり、その全てを本文書では、全ての目的のために、参照を以って記載加入とする。
一般に本当の問題が摩擦の増加、または真空と摩擦の組み合わせである場合、人々は貯蔵キャニスタを開くのに伴う問題について誤って真空のせいにする可能性がある。いずれにせよ、結果は開封が困難または不可能なシールされた容器である。
蓋110は、中心軸の周りに蓋110を回転させることにより、コンテナ本体112に可逆的に結合するように構成され、蓋110がコンテナ本体112に部分的に取り付けられたままになるように、断熱キャニスタアセンブリ100を開閉又は部分的に開くことができる。例えば、使用者は、蓋110を時計方向にねじ込んで断熱キャニスタアセンブリ100を閉じ、蓋110を反時計方向に回転させて、断熱キャニスタアセンブリ100を開くかまたは部分的に開くことができる。しかし、他の例では、他の開閉技術が用いられることもある。
本明細書でさらに説明するように、蓋152の要素は、シール機構を嵌合ねじ190の回転から切り離すことによって、蓋152とコンテナ本体154との間の摩擦を低減することもできる。蓋152のさらなる図は、図2A(斜視図)及び図2B(断面図)に示される。結合リング195及びガスケットタブ198のような付加的な構成要素が示され、図3A、図3B及び図4に関してさらに詳しく議論される。
結合リング195は、ガスケット185と嵌合スリーブ172の両方に結合されてもよい。図3Bは、嵌合スリーブ172、ガスケット185、及び結合リング195を含む蓋152の分解図を示す。ガスケット185は、結合リング195に対して所定の位置に固定される。しかしながら、結合リング195は、嵌合スリーブ172の周囲で自由に回転するように構成され得る。例えば、結合リング195と嵌合スリーブ172の両方がポリカーボネート製であり得るので、結合リング195とガスケット185は、互いに本質的に静止している一方、結合リング195と嵌合スリーブ172は互いに円滑に回転する。
むしろ、嵌合ねじ190は、回転力を軸力に変換し、ガスケット185が内壁162に沿って回転するように揺動することなく、ガスケット185をコンテナ本体154から効果的に持ち上げ、したがって、ガスケット185とコンテナ本体154の摩擦力を緩和する。むしろ、ガスケット185は、嵌合ねじ190が嵌合突起205に係合し、係合解除するにつれて、上下に移動する。
中央空洞部166内の真空の発生は、ガスケット185に引く力を与え、ダイヤフラムチャンバ186内の圧力を低下させる。従って、ダイヤフラムチャンバ186内の負圧は、外部空気で埋め戻され、該外部空気はOリング通路220を介してキャニスタアセンブリ150内に入り、嵌合突起205間のギャップを横切り、結合リング195内の割れ目によって作り出された空気通路210を介して空気通路188内に入る。その後、蓋152は、過度の真空または摩擦の力なしに除去されることができる。
